IMPROVED JOURNAL-BOX.

Specification forming part of Letters Patent No. 97,96@q dated December1 1, 1669.

To a/ZZ whom t may concern:

Be it known that I, AMBnosn H. SAssA- MAN, of Scranton, in the county ofLuzerne and State of Pennsylvania, have` invented a new and valuableImprovement in Anti-Friction Machinery, (Box, 85o. and I do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theannexed drawings, making a part of this spreiication, and to the lettersand figures of rel'- erence marked thereon.

Figure l ofthe drawings is arepresentation of a longitudinal section ofmy device. Fig. 2 is a cross-section of the same.

My invention relatesto journalboxes and shafts for cars and machinery y`and it consists, mainly, in the construction and arrangement of a seriesof grooves both in such shaft and box, in which I adjust a continuousseries of loose rollers, so arranged that they shall rotate in saidgrooves without axles or pivots, the object being to lessen friction,and thereby save the labor and expense of lubrication.

My journal-box is formed in two sections, which on the drawings aremarked A and B, respectively. On the inner sides of these sections I cutgrooves, usually three in number, leaving anges between them to serve asguides for the rollers, hereinafter mentioned. My shaft is alsoconstructed with grooves of Suitable depth and of a length and in numbercorresponding with the grooves formed in the journal-box abovedescribed. Vhen adj usted in place, the grooves in the shaft aredirectly opposite the' grooves in the box.

rIhe letters a are small rollers arranged in the grooves of the box andthe shaft. They have no axles or pivots, and are guided in theirmovements by the flanges upon the box and shaft formed by cutting outthe grooves above mentioned. These rollers ll the entire spaces formedby the grooves of the box and shaft, leaving only a small space betweentheir ends and grooved flanges and a very small space betweenthemselves. They are so arranged that they touch each other when atrest, leaving only a minute space between the two rollers immediately atthe top of the shaft.

What I claim as my invention, and desire to secure by Letters Patent, isn The combination and arrangement of the grooved journal-box and shaftherein described with the rollers ct, all constructed and operatingsubstantially as and for the purposes specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

A. H. SASSAMAN.
